HST North fields #1

Open martinkilbinger opened 2 years ago

martinkilbinger commented 2 years ago

The UNIONS footprint overlaps with some HST fields:

DEEP2/DEEP3, in W3, part of the 3DHST data. We have used these data to calibrate photometric redshifts.
AEGIS, see below. HST imaging, spectroscopic data is DEEP2/3.
GOODS-North. Unfortunately only one r-band tile is overlapping.

Goals

add spectroscopic calibration data.
assess blending
improve star-galaxy separation.

3DHST-AEGIS field and overlapping UNIONS tiles.

I spoke to some people who use HST more than I do, and they said that the star-galaxy separation would be reliable to magnitude 27 or 28, so that should be more than enough for for us
